中文摘要: 本项目拟以新方法、新材料突破为主导,针对目前有机聚合物体异质结太阳能电池活性层形貌普遍存在低有序度、大尺度聚集以及有限的形貌优化手段等现状,开展利用超分子自组装协同诱导效应的方法构筑理想结构活性层的相关工作。该方法在溶液加工过程中,利用具有超分子自组装性能的富勒烯衍生物预组装形成的有序结构为受体模板,并通过聚合物给体材料与该受体模板间的协同诱导作用力形成长程有序、纳米尺度相分离、连续传输通道的层状结构共混活性层。这种新型的受体材料相对于目前普遍研究的受体材料(例如,PCBM)来说具有更广的应用范围,通过溶液旋凃加工方法以及受体模板的诱导效应来构筑的理想活性层,不仅可以使大量无定型给体材料实现有序排列并形成连续的传输通道,而且避免了热退火等繁琐的后处理工艺。以这样一个全新的理念去探索理想活性层形貌的构筑方法,以及形貌对太阳能电池性能影响,最终有望获得取代PCBM的高性太阳能电池受体材料。

英文摘要: The active layers of bulk heterojunction structure polymer photovoltaic cells are mainly face with the low ordered, large scale aggregation morphologies and limited methods for morphology optimizing. In order to obtain an ideal active layer morphology,we want to utilize superamolecular self assemble synergistic induction method for morphology optimizing. In this project, we design and synthesis a series of fullerene derivatives as acceptor materials which can form high odered structure by superamolecular self assemble method during the solution process. The acceptor material with high odered structure is viewed as acceptor template, which can assist and induce the donor materials to form long range ordered, nanoscale phase separation and p-n continuum channel active layer by the force of superamolecular synergistic induction between acceptor template and donor material. This method can be applied in more widely area, not only can arrange the amorphous donor materials in an order, but also can avoid the fussy post-processing.According to this novel concept,we want to investigate the relationship between the morphology of active layer and the performance of solar cell,then obtained new acceptor materials with high solar cell performance, which can substitute PCBM.
